1 Claim. (01. 110-97);

This invention relates to improvementsin attachments adapted to beincorporated in, heating furnaces, said attachment providing for asaving in fuel, and a more rapid heating of the wa ter or air in thefurnace, thus providing a more eflicient and effective furnaceoperation.

] An object of my invention baffles suitably supported in the furnacethe proper distance above the fiame in the furnace,

whereby the baffles will be heated to a red hot temperature, andconsequently heat the water or air in the furnace more quickly, andinthe use of oil heat, after the thermostat in the heating systemhas cutthe oil burner off, the heated baflles will retain the heat in thefurnace for a considerable time, thereby delaying the cooling of thewater or air, so that the next time the oil burner turns on, will bevery materially longer between burner operation, than would be the caseif the bafiles were not employed,

Another object of my invention is to provide a plurality of spaced heatretaining baffles suitably supported in a furnace and extending throughthe restricted opening in the transversely extending water partition,whereby allof the heated particles of combustion as they pass to thestack opening, will engage and circulate about the spaced bafiles toheat them red hot, thus more quickly heating the water in the heatingsystem, and storing up heat in the furnace to provide for less frequentoperation of the oil burner in the furnace, and a lesser period ofoperation of the said burner, with a consequent saving in fuel cost.

A still further object of my invention is to provide an improved baflieconstruction in a hot water or hot air furnace which may be incorporatedin any house furnace to provide a more efficient operation of thefurnace, with a very small cost for the installation of the baffles.

In the accompanying drawing which constitutes a part of my application,

a modified ll. out the following specification and the accomis toprovide metal Other objects will appear as the description Figure 1 is avertical sectional view through a panying drawing to designatecorresponding parts.

In carrying out my invention, I provide a suitable hot water furnacehaving a body portion l with spaced innerand outer Walls 2 and 3,respectively, and with a transversely extending hollow water partitionadjacent the upper portion of the body, said partition being formed witha restricted opening 4, through which theparticles of combustion willhave to pass in their travel to the smoke stack opening 5. A suitablefurnace head 6 also formed with spaced walls is provided and will'bereceived on the upper end of the furnace body I, and will havecommunication with the hollow body, so that the watermaycirculatethroughout every portion of the furnace.

An oil burner l is illustrated in Figure 1 of the drawing, and will bereceived within the lower end of the furnace body I, although myinvention will work with high eflicienoy with the so-called gun type ofburner.

I have illustrated my preferred form of heat retaining baffle 8 as beingsubstantially rectangular in shape, but with the lower end portionsflared outwardly as at 9. An opening ID will be formed in each baflie 8,through which the supporting rod II will be received. From Figure 1 ofthe drawing, it will be seen that Ihave provided a pair of seats I2 andI3 at the opposite sides or ends of the restricted opening 4 in thepartition porting bar or rod H, and the various baffle plates 8 willbesuspended upon the rod I l in spaced relation, and suitable spacingwashers IE will be provided to slide over the rod l l between adjacentbafile plates. It will be further seen that the restricted opening 4will be substantially filled with the baffles, there being suflicientspace between adjoining bafiles for the smoke and particles ofcombustionto pass to the smoke stack opening,

and also that the lower end portions of many of 1 ,the baffles are bentlaterally to permit the baffles to occupy practically the whole crossarea of the furnace, so that they will be heated by contact with theflame from;the oil burner. The baffles will be positioned a sufiicientdistance above the oil burner, to prevent the forming of soot upon i thebaffles, which would clog up the furnace and 14 which will be adapted toreceive the cross supopening 23 is formed in the bar 22, in order thatthe same may be supported upon the rod or bar II. This form will workvery satisfactorily with thefgun type of burner, and will be supportedin position below the partition l4, whereby the heat may be stored inthe convolute winding to retain the temperature in the furnace. for alonger period, thus providing for the lesser time of burner operation,and a longer period of time between burner operation.

Many minor changes in detail of construction may be resorted to withoutdeparture from the spirit of the invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States is: In a heating furnacehaving a cross partition with a restricted opening for the passage ofparti-cles of combustion, furnace heating means, a plurality of flaredheat storing bafiies supported in said opening and extending above andbelow the same, spacing means between said baffles, and the lower endsof said baflles being outwardly flared and laterally bent tosubstantially fill the cross area of the upper portion of the furnacefire box and to be heated by direct contact with the flame of thefurnace heating means.
